An example that uses threads (and not adpapi) is in January's mail achive, at: http://twistedmatrix.com/pipermail/twisted-python/2003-January/ 002694.html Here's some old code that uses adpapi (save as a .rpy): ### from twisted.web import resource from twisted.web.server import NOT_DONE_YET dbname = 'test' dbuser = 'dbuser' dbpass = 'dbpass' from twisted.enterprise import row class FooRow(row.RowObject): rowColumns = [ ('foo_id', 'int'), ('name', 'varchar'), ('weight', 'int'), ] rowKeyColumns = [('foo_id', 'int4')] rowTableName = 'foo' #rowFactoryMethod = ['testFactoryMethod'] def databaseResult_adbapi(result, httpRequest): if result: for foo in result: httpRequest.write('foo: '+str(foo.__dict__)+'<br/>') else: httpRequest.write('stop:') httpRequest.finish() def errBack_adbapi(err, httpRequest): httpRequest.write('error: '+str(err) ) httpRequest.finish() class MyResource_adbapi(resource.Resource): def render(self, request): from twisted.enterprise import adbapi, reflector from twisted.enterprise.sqlreflector import SQLReflector dbpool = adbapi.ConnectionPool('pyPgSQL.PgSQL',database=dbname,user=dbuser,passwo rd=dbpass) r = SQLReflector(dbpool,[FooRow]) d = r.loadObjectsFrom('foo',whereClause=[('foo_id', reflector.LESSTHAN, 5)]) d.addCallback(databaseResult_adbapi, request) d.addErrback(errBack_adbapi, request) return NOT_DONE_YET resource = MyResource_adbapi() ###

I've been pouring through the docs and examples, but can't find an example of a .rpy that generates a page containing the results of a database query. How would such a thing be properly architected? Clearly the adbapi would be involved, but then how do I get the query results into the string returned by my resource? Or would I use a deferred instead?

Would someone please share a little code snippet (or point me at one)illustrating how that would best be accomplished?

Thanks.
